- multiDownload now accepts objects with url+filename instead of just URLs
- Maintains backward compatibility with old URL-only format
- fileDownloader passes full item objects to multiDownload
- Fixes issue where dotted filenames weren't used
- Also fixes dialog close error and missing translation
